Hi I recently aquired a YZ125 2007 model,I drained the oil from the motor,and was told to fill the engine,till the oil comes out the screw,whole on the foot brake side of the motor,at the front .Is this correct,or should you just measure the oil out and that is the correct measurement?There was close to a litre that came out of the motor,I filled the motor up until it came out of the screw whole,and it only took 300ml or so ,is this correct,the way I have done it ? Cheers Glenn
